Abstract

Whilst many content adaptation operations exist and a
number of different approaches are currently being
proposed, selecting the right content adaptation operation
is largely an ad hoc process. In this paper we discuss
issues pertinent to content adaptation operations and in
particular the process of their selection by taking the view
that a selection process needs to be informed both by the
results of the evaluation of generated content and the
analysis of the content. The discussion is made in the
context of MPEG-21 which supports both Quality of
Service (QoS) and user priority preferences, the
combination of which are essential for instituting a
process of selection of appropriate adaptation operations.
